Beware old fashioned mail theft scams

A $120,000 superannuation theft has prompted police to warn superannuation and investment self-managers to keep an eye on their transactions.

Police arrested a 35-year-old man in Brisbane on Tuesday after he allegedly tapped into a man's superannuation fund and took $120,000.

Police allege the man gained access to the victim's fund and withdrew large sums of money.

The 62-year-old victim noticed the problem when he could not gain access to his superannuation account.

The alleged offender was charged with fraud and dealing with identification particulars.

Queensland Police Fraud and Corporate Crime Group Detective Superintendent Brian Hay said people who managed their own investments and accounts needed to be extra cautious.

"While we focus quite heavily on internet scams and securing your identity online, sometimes we forget scams like this can occur from old fashioned mail theft," he said.

"Someone may steal your bank statement out of your mail box and use those details to gain access to your money.

"Consider online statements, but when moving to an online source, do not respond to emails from banks or funds requesting you update your password or details and go the extra mile and do further checks when contacted by your institution."
